Care should be taken to ensure Swimlane traffic cannot be intercepted in transit. Swimlane web traffic should be secured in transit using TLS/SSL in IIS.

If a single Swimlane server deployment is used, the database ports of 2424, 2480, and 27017 can be blocked to restrict external database access. If MongoDB is located on a separate server, or if multiple database servers are used, consider using TLS/SSL for transport encryption of data in transit between the database servers and the Swimlane servers.
